I haven’t seen a single ad since the moment I installed Firefox and clicked “don’t suggest stuff”.
Yes, I am willing to pay say 100$/year for web browser if money would entirely go to development. Maybe something to support staff like CEO. But not over 5 000 000 per year ( see https://en.wikipedia.org/wiki/Mitchell_Baker#Negative_salary... )
And if such browser would be actually user-first, without ads for VPN and Disney movies (especially without ads pretending to not be ads).
Then it appears they recently added an additional sponsored option, and defaulted it to enabled, in an update, even for users like myself who had every other sponsored option disabled.
They're hardly the only organization that does this, but it is extremely disappointing. Were Firefox not the only major browser with very useful extensions, I'd certainly switch to something else.
